Abstract: PURPOSE: To make the depth of drawing shallow and to save the material consumption, by installing a fixed die face and a movable die face on an upper die.  
     CONSTITUTION: After setting a material 12 on the uppper surface of a blank holder 7, an upper die 5 is moved down so as to hold the material 12 by a movable die  face 9 having point a 2 . Next, by successive downward movement of the die 5; the  bottom end b 2  of the die 5 contacts with the material 12; and finally a fixed die  face 5a coincides with the movable die face 9. A preparative forming of the material 12 is performed during the processing from the material holding to the coincidence of the die faces 5a and 9. By further downward movement of the die 5; the  drawing work is performed accompanied with the downward movement of cushion  pins 8. Thus, the material 12 is already held when the point b 2  contacts with the  material 12, by allowing the point a 2  movable and by keeping the relation A 2 >B 2   at the beginning of holding the material; and the relation C 2 ≤B 2  is kept at the  moment of the completion of the drawing work, because of the result that the die  face 9 moves upward relatively to the upper die; accordingly, the necessary depth of  drawing can be made smaller, and that causes the saving of materials.

Title: Head positioning device
Inventor: YOKOUCHI HIDEYA
IPC: G11B21/02
Filed: 1987-06-03
Abstract: PURPOSE:To realize the positioning of a magnetic head at the time of moving the head with high accuracy optimum for flexible disk drive with an inexpensive slide bearing, by performing the movement of the magnetic head with a pinion provided on the shaft of a permanent magnet type stepping motor and a rack provided on a carriage on which the magnetic head is loaded. CONSTITUTION:Since an attractive force between a rotor and a stator is applied on entire circumference uniformly by adopting the permanent magnetic type steeping motor of full arc integration type as a stepping motor 11, a radial force being applied on the bearing 21 of the stepping motor 11 is negated, and is reduced. Therefore, it is possible to reduce the friction torque of the bearing 21 even when the slide bearing having friction larger than that of a ball bearing is used as the bearing, and the worsening of the positioning accuracy of the stepping motor 11 when it stops can be reduced. In such a way, it is possible to obtain an inexpensive head positioning device with high accuracy optimum for the flexible disk drive.

Abstract: PROBLEM TO BE SOLVED: To easily control a fogging phenomenon by varying developing bias voltage in plural steps between a maximum value and a minimum value decided previously based on a control signal from a developing bias voltage control signal output means. SOLUTION: When a user performs key operation for increasing or decreasing the developing bias voltage, developing bias control data stored in an EEPROM is rewritten and developing bias control voltage supplied to the terminal 54 of a developing bias voltage varying circuit 43 is changed. Therefore, the collector voltage of the phototransistor PT1 of a photocoupler 44 is changed, and the developing bias voltage outputted to a developing device 23 from a developing bias voltage output circuit 42 through a terminal 51 is changed. For example, if the developing bias control voltage is changed by every 0.5 V from 1 V to 5 V by changing the developing bias control data by one step by the key operation in an operation part, optional developing bias is set and the fogging phenomenon is easily controlled.

Filed: 1995-06-06
Abstract: PURPOSE: To detect various abnormalities of armature winding easily by comparing the oscillatory rotational angle of a dancer arm at the time of winding and hooking a wire with a preset oscillatory rotational angle at the time of normal winding and hooking. CONSTITUTION: A wire 3 is subjected to different tension at the time of winding and hooking operation of a flyer 5. A dancer arm 30 oscillates and rotates such that the tension is balanced with the force of a spring 34 to eliminate slack of the wire 3. Pulses are outputted from an encoder 33 in the positive and negative directions and the number of pulses is stored sequentially in a sequencer. It is then compared with the number of pulses being outputted from the encoder 33 at the time of normal winding and hooking and stored in the sequencer. When the difference deviates from a preset allowable range, a decision is made that the winding is abnormal. This apparatus can detect abnormal winding due to incorrect shape of armature core, hooking miss, etc.
